I had no idea there were ribs near your neck. Ty worked on me a little yesterday, but the mouseitis is back. I need to make my desk more ergonomically correct. My desk chair is one of those huge executive chairs. I had it sitting pretty low so I was always holding my arm up high to reach the mouse. Ty couldn't comprehend why I had my chair so low. Well, I will tell you why: if I raise it and sit all the way back in my chair my feet don't quite lay flat on the ground. But I guess I would rather not touch the ground than have mouseitis.
I googled mouseitis to see if anyone else had this problem and to see if it had a technical name. Turns out the technical name is mouseitis and it is common, kinda like carpal tunnel. And here I thought I was being so cute and termed the name mouseitis! :)
